# Course #157: Introduction to Evil-WinRM$
## Overview
In this section, we will dive deep into Evil-WinRM$, a powerful tool designed for Windows Remote Management (WinRM) pentesting. With the increasing prevalence of WinRM in enterprise environments, mastering Evil-WinRM$ can significantly enhance your penetration testing toolkit.
## 1. Installation and Configuration on Kali Linux
### Prerequisites
Before you can use Evil-WinRM$, ensure that you have the following prerequisites installed on your Kali Linux system:
– **Kali Linux (latest version)**: Always ensure you're using an up-to-date version of Kali.
– **Ruby**: Evil-WinRM$ is a Ruby-based tool, so Ruby must be installed.
– **WinRM Enabled on Target**: Ensure the target Windows machine has WinRM configured and accessible.
### Installation Steps
1. **Update Your System**
Open a terminal and update your system packages:
sudo apt update && sudo apt upgrade
2. **Install Ruby**
If Ruby is not installed, you can install it using:
sudo apt install ruby
3. **Install Evil-WinRM$**
You can install Evil-WinRM$ by cloning it from the GitHub repository or using RubyGems for installation. Here’s how to do both:
– **Using GitHub Repository**:
git clone https://github.com/hackerhousey/Evil-WinRM.git
cd Evil-WinRM
sudo gem install bundler
bundle install
– **Using RubyGems**:
sudo gem install evil-winrm
4. **Verifying Installation**
To ensure that Evil-WinRM$ is installed correctly, run the following command:
evil-winrm -h
If installed correctly, you should see the help message displaying usage options.
## 2. Step-by-Step Usage and Real-World Use Cases
### Connecting to a Target System
Now that we have Evil-WinRM$ installed, let’s use it to connect to a target Windows system.
#### Basic Usage Syntax
The syntax for connecting to a target machine is as follows:
"`bash
evil-winrm -i
"`
#### Example Connection
1. **Using a Username and Password**:
Suppose you want to connect to a target with an IP address of `192.168.1.10`, username `Administrator`, and password `P@ssw0rd`. The command would be:
evil-winrm -i 192.168.1.10 -u Administrator -p 'P@ssw0rd'
2. **Using NTLM Authentication**:
If you have a valid NTLM hash, you can authenticate using it. The command would look like this:
evil-winrm -i 192.168.1.10 -u Administrator -H 'NTLM_HASH'
3. **Using Kerberos Authentication**:
For Kerberos authentication, ensure you have the `kinit` command set up correctly. Use the following command:
evil-winrm -i -u -k -s
### Real-World Use Cases
Evil-WinRM$ can be used in various real-world scenarios, including:
– **Post-Exploitation**: After an initial exploit, you can leverage Evil-WinRM$ to maintain access or perform lateral movement within a network.
– **Penetration Testing**: Use Evil-WinRM$ during pen tests to exploit WinRM vulnerabilities and gain remote shell access.
– **Incident Response**: Security professionals can use Evil-WinRM$ to investigate and respond to incidents involving compromised Windows systems.
### Advanced Features
Evil-WinRM$ also offers advanced features like:
– **Interactive Shell**: Provides an interactive command shell once connected to the target.
evil-winrm -i 192.168.1.10 -u Administrator -p 'P@ssw0rd'
– **Uploading and Downloading Files**: You can upload files to the target and download files from the target.
– **Upload a File**:
upload /path/to/local/file C:pathtoremotedestination
– **Download a File**:
download C:pathtoremotefile /path/to/local/destination
– **Running PowerShell Commands**: You can execute PowerShell commands directly from Evil-WinRM$.
ps 'Get-Service'
### Technical Explanations
#### Understanding WinRM
WinRM (Windows Remote Management) is a Windows feature that allows for remote management of Windows machines. It uses WS-Management protocol and is based on SOAP (Simple Object Access Protocol). Knowing how WinRM works is crucial for understanding the capabilities and limitations of Evil-WinRM$.
#### Authentication Mechanisms
WinRM supports several authentication methods, including:
– **Basic Authentication**: Uses a username and password sent in clear text (not recommended).
– **NTLM Authentication**: More secure, uses a hashed token.
– **Kerberos Authentication**: The most secure method, allowing for single sign-on capabilities.
Understanding these authentication methods is critical for using Evil-WinRM$ effectively.
